配偶选择涉及处理信号，这些信号可以达到很高的复杂性，并具有多个组成部分，即使在大脑很小的小动物中也是如此。这就提出了这样一个问题：这些生物是否以及如何处理这种复杂性。一种解决方案涉及组合处理，即将不同的信号元素作为单个单元处理。组合处理已经在几种哺乳动物和鸟类中被描述过，最近在一种振动信号昆虫——Enchenopatreehoppers中也被描述过。在这里，我们研究了连续变化信号特征的组合规则和配偶偏好之间的关系。Enchenopamale广告信号由两个元素组成：一个“呜呜声”，接着是一组脉冲。哀鸣的主导频率和元素组合对雌性都很重要。我们向enchenopa雌性提供了不同元素顺序（自然[哀鸣脉冲]，反向[脉冲-哀鸣]）和频率的合成信号，并记录了它们的反应。相反的组合导致了信号吸引力的下降，也稍微改变了频率偏好的形状。我们发现雌性可以分为三种“类型”：既有强烈偏好又有强烈组合规则的雌性，既有弱偏好又有弱规则的雌性，以及既有强烈偏好又有弱规则的雌性。我们的研究结果表明，在enchenopasignal处理过程中，配偶对连续信号特征的偏好“优先”于组合规则，但也与组合规则相互作用。根据择偶决策的选择，偏好和规则之间的关系可以演变成不同的形式。我们认为，在具有更复杂信号的物种中探索这种偏好和规则之间的关系，将有助于深入了解多组分通信系统的进化。
Mate choice involves processing signals that can reach high levels of complexity and feature multiple components, even in small animals with tiny brains. This raises the question of whether and how such organisms deal with this complexity. One solution involves combinatorial processing, whereby different signal elements are processed as single units. Combinatorial processing has been described in several mammals and birds, and recently in a vibrationally signalling insect,Enchenopatreehoppers. Here, we ask about the relationship between combinatorial rules and mate preferences for continuously varying signal features.Enchenopamale advertisement signals are composed of two elements: a ‘whine’ followed by a set of pulses. The dominant frequency of the whine and element combination both matter to females. We presented synthetic signals varying in element order (natural [whine-pulses], reverse [pulses-whine]) and in frequency toEnchenopafemales and recorded their responses. The reverse combination resulted in a decrease in attractiveness of the signals, and also slightly changed the shape of the preference for frequency. We found that females could be classified into three ‘types’: females with both a strong preference and a strong combinatorial rule, females with both a weak preference and weak rule, and females with a strong preference but a weak rule. Our results suggest that inEnchenopasignal processing, the mate preference for a continuous signal feature ‘takes precedence’ over, but also interacts with, the combinatorial rule. The relationship between the preference and the rule could evolve to take different forms according to selection on mate choice decisions. We suggest that exploring the relationship between such preferences and rules in species with more complex signals will bring insight into the evolution of the multi-component communication systems.
